James Corden Models, Scolds Host on 'The Price Is Right'

When caught on-air at one point with his fly down, Corden said, "Don't worry guys, the cage is open, but the beast is asleep."

On The Price Is Right, "Big Money Week" means big guest-stars — like James Corden.

The Late Late Show host stopped by the CBS game show on Monday night, filling in briefly for the series' second-ever male model, James O’Halloran.

O’Halloran shared a few pointers with Corden about how to properly showcase a prize when taping a live episode. The comedian especially was fascinated with how much of the display actually consists of unwinnable props.

During the episode, Corden showed off his dance moves and posing expertise, as well as overwhelming enthusiasm for winners that spurred him to lift them up into the air.

He also scolded Price Is Right host Drew Carey when a contestant lost, and was caught on-air at one point with his fly down. "Don't worry guys, the cage is open, but the beast is asleep," he told the audience.

Corden compiled the highlights into a video that aired on Monday's Late Late Show. Watch it below.
